Since August 1, 2022, people who test positive no longer have to enter
quarantine and can, if they do not feel sick, participate in most
aspects of public life. In accordance with government regulations,
these people are subject to requirements for free movement and a
general requirement to wear an FFP2 mask. Entry prohibitions apply in
especially sensitive areas.
